PROSPECTUS SUPPLEMENT NO. 42

(to Prospectus dated May 4, 2024)

MSP RECOVERY, INC.

32,220 Shares of Class A Common Stock

This prospectus supplement no. 42 amends and supplements the prospectus dated May 4, 2024 (as supplemented or amended from time to time, the “Prospectus”), which forms a part of our Registration Statement on Form S-1 (No. 333-268616). This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on September 29, 2025 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

This prospectus relates to the offer and sale from time to time by the selling securityholders named in this prospectus (the “Selling Securityholders”), or their permitted transferees, of up to 32,220 shares of our Class A Common Stock, par value $0.0001 per share, held by the Selling Securityholders (the “Total Resale Shares”), including up to 15,239 shares of our Class A Common Stock issuable upon exercise of the Class A Common Stock Underlying Warrant (the “CPIA Warrant”) pursuant to an Amendment to the Claim Proceeds Investment Agreement (the “Amendment”) and a Warrant Agreement (the “Warrant Agreement”) with Brickell Key Investments LP (the “CPIA Holder”). As the exercise price of the CPIA Warrant is only $0.4375 per share, should the CPIA Holder exercise the CPIA Warrant, we would only receive nominal proceeds therefrom.

Our Common Stock, Public Warrants and New Warrants are listed on Nasdaq under the symbols “MSPR,” “MSPRZ,” and “MSPRW.” On September 26, 2025, the closing price of Common Stock was $1.39 per share, the closing price of our Public Warrants was $0.0151 per warrant and the closing price of our New Warrants was $0.0018 per warrant.

Effective at 11:59 PM EDT on September 1, 2025, the Company amended its Second Amended and Restated Certificate of Incorporation filed with the Secretary of State of the State of Delaware to effect a 1-for-7 reverse stock split of the Company’s common stock (the “Reverse Split”). Unless otherwise noted, the share and per share information in this Prospectus Supplement No. 42 have been adjusted to give effect to the Reverse Split.

Investing in our securities involves risks. Before you invest in our securities, please carefully read the information provided in the “Risk Factors” section beginning on page 9 of the Prospectus and any in any applicable prospectus supplement, and Item IA of our Annual Report on Form 10-K for the fiscal year ending December 31, 2024, filed with the SEC on April 16, 2025.

Neither the SEC nor any state securities commission has approved or disapproved of the securities to be issued under the Prospectus or determined if the Prospectus or this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is September 29, 2025.
